How big a buzz are you getting from your morning coffee? Pretty big. Probably not as much as you might get from the java being billed as the strongest called death wish coffee and has twice the caffeine. Gio benitez is here with the buzz. It smells great. You can feel it. What about that name death wish coffee. Yeah. Well, this morning the maker of death wish coffee says it's so powerful you'll only need one cup a day. But people all over are asking is it safe to drink that much caffeine? If regular coffee doesn't pack enough of a punch, would you drink this, coffee beans packaged with a skull and cross bones. The name, death wish. When it comes right down to it it's just a very strong cup of coffee. Reporter: That's mike brown, the founder and owner of what he calls the strongest cup of coffee in the world. He uses beans that give you twice the jolt, doubling the caffeine in your average cup. That's where he got the fame death wish. We're making the world's strongest coffee. Can't call it puppies or kittens or anything like that. Reporter: Lots are talking about caffeine. Monster energy drinks will soon begin listing caffeine content on its cans. Here's how much caffeine we're talking about.

But the same amount of death wish coffee, about 660 milligrams of caffeine.

Reporter: At his coffee shop in upstate new york, brown only sells the beans. He doesn't brew death wish coffee there, not yet and when i asked if he drinks this super coffee -- yeah, I grifk it only on the mornings when I need to get a lot of stuff done and dragging. No, I can't handle it every morning. Reporter: Well, certainly tastes friendly and while dr. Besser says it's like having two cups of coffee at once, if you're the kind of person that has ten cups a day, imagine how much caffeine you're getting into your system if you're drinking some of this stuff, we have it here and you can see the logo. Sam is enjoying it. I love it. I think it's fantasti I recommend everyone stay tuned to this broadcast. About 20 bucks a pound. Oh. For me I will -- you're a connoisseur. To me it's a very smooth cup of coffee. Now, check with me in about 15 minutes and see if I'm in the corner hugging myself. Suddenly jittery. Exactly. We'll check back with you. Tastes good. In the meantime, ladies and gentlemen, spring wants you to
